Good overall fin, but at the same time nothing special about them.

By Isaac O.

The sessions I had on these fins were in hollow critical type waves so I was more thinking about just surfing and making my waves then being critical of the fins. All I know is they worked really well. Made lots of nice late drops. Got some nice tubes. Some nice tight snaps in some steep sections. Never had a chance to lay any long arcing carves so never got a chance to really feel the nuances of the fin in that regard. Aside from that I was pretty much able to just surf the way I wanted and not really think about what the fins were doing, which is a good thing.
